I am a pure CPA buyer, so, I agree, that I don't worry much about fraud. The big money is in brands. P&G goes on a 6-month blitz making sure every man knows about the fusion razor, and the person that cleans the house knows what a swiffer is. They use an ad blitz to secure shelf space and consumer interest, then print money hand over fist for the next decade. As a CPA buyer, I personally welcome rampant ad fraud because it keeps the people with real money like P&G from bidding up ad prices. Ad fraud screws brands and publishers. It helps CPA advertisers, because it keeps the brand money out of the system.
